Paper Title
Series Compensated Transmission Line Fault Location Using Gps Synchronized Voltage Measurement

Abstract
The transmission line faults are very often occurred and destroy the quality of power being transmitted through the transmission line. The detection of faults in a transmission line using measurement of voltage or current using current transformers is very common but its efficiency is limited by the efficiency of the current transformers which seems very poor. In this paper a new algorithm is presented for fault location in series compensated transmission lines with Fixed Series Capacitor (FSC). The time domain modeling of a transmission line and FSC system are used in this proposed algorithm. The series compensated lines have limitations with metal oxide varistor (MOV) operation, prefault system condition, and high resistance fault and shunt capacitance. The measurement of voltages may be done using GPS technology for accurate synchronization. This paper gives a fault-location method for transmission lines using only synchronized voltage measurements at both ends of the line which eliminates the inherent errors due to current transformers. This method is applicable for both transposed and un-transposed lines. This method is tested using results from a steady state fault- analysis program and EMTP, and generated voltage signals are preprocessed, and phasor are estimated through DFT algorithm in the MATLAB. Keywords - Fault location, bus impedance matrix, EMTP, Fault analysis, Synchronized phasor measurement, DFT, Series Compensation.
